MACHINEFOR BENDING PRINTERS RULES.

"w SPECIFICATION forming To` all whom @t may concern:

Beit known that I, CHARLES V. STEINRACH,

i of the city, county, and State ot'` New` York,

have invented certainnew and useful Improvements inMachines'forBendingPrinters"Rules,

of which `the following is a specification.

, This invention has ret'erenceto an improvedinachinc for bending brassrules, leads, dac., to

' `any desired degrveot' curve for` use in printing-oices, so as to doaway with the difficult manipulation of the rules by hand, produce a.more regular and uniform curvature, and dispense with the loss ofmaterialincidental tothe inetcient mechanical appliances `heretoforeused for this purpose.

. The invention consists of a machinefor bending printers rules, whichsupports in suitable bearings on a xed standard an upper ribbedcurving-cylinder, which is revolved by a handcrank and supported inbearings of side standards, of which one is laterally movable andcapable of being thrown sidewise, so as to remove conveniently smallrules bent into circular shape. Below the upper bending-'cylinder arearranged two smooth bendingrolls,which are supported on avertically-adjustable frame, that is hinged at its rear end to a fixedarm of the supporting-standard and provided back 'of the bending-rollsand cylinder. with a platv sponding parts.

By reference to the drawings, A represents the main standard of myimproved machine for bending printers rules, which standard is providedwith a circular base-ange for being scr'ewed'to'a bench or othersupport.

. From the main standard A extends in one direction a straight arm, A',and in opposite rolls B.

with the main standard A.

direction thereto a second upwardlycurved arm, A2, to which is hinged aroller-carrying frame, B, that carries at its central part two smoothbending-rolls, B'. The roller-carrying frame B is adjusted at its frontend by means of a vertical set-screw, a, carried by the arm A', saidAset-screw being turned by a handwheel at the lower end. The adjustableframe B is furthermore provided, back ot' the bendingrolls B', with axed horizontal platform, C, and a side gage, C', along which the rulesare moved and guided toward the bending- The main standard A isfurthermore provided at both sides ot' the frame B with vertical sidestandards, D D', which support in suitable journal-bearingsintermediately above the rolls B'- a curving-cylinder, E, that isarranged with longitudinal ribs and revolved by a hand-crank, E',secured to one end of its shaft.

The side standard D is preferably, like the arms A A2, cast in one piecewith the main standard A, while the standard D', at the opposite side ofthe same, is made laterally movable, being guided by means of alaterally-extending and slotted base, d, along a fixed transverse pin,d', supported by sidewise-extending lugs or brackets D2, which are castin onepiece rlhe inner ends of the lugs D2 are provided withinwardly-projecting portions d2, which overlap the base l of the movablestandard D', and retain the same firmly when in position for supportingthe shaft of the curving-cylinder E, as shown in Figs. 3 and 4. When theside standard D' is moved sidewise, clear of the projections d2, untilits slotted base cl2 is stopped by the xed pin d', it can be swung onthe pin d downward until stopped by aixed stop-pin, d3, on standard A,and retained thereby in horizontal position. When the movable sidestandard D' is thus moved ont of the way small rules which have beenbent into circular shape can be readily removed from between the rollswithout in the leastinjuring the completeness of their shape.

When bending larger arc-shapedcurves it is not necessary to throw thestandardA sidewise and downward, as the rules can be removed at theopposite side of the rolls. The degree IOO of curve, whether plain orserpentine,'is constantly under the control of the operator, who adjuststhe set-screw to suit.

The machine is simple, solid, and powerful, and permits the bending ofrules ot' all kinds rapidly and conveniently into accurate and gracefulcurves or entiie circles, resultin gin a saving of time in bending, andin the production of better work in printing.

Having thus described my invention, Iclaim as new and. desire to secureby Letters Patent- 1. In a machine for bending printers rules,

the combination ot' smooth bending-rolls supported in avertically-adjustable framel with a ribbed curving-cylinder above thesame, and with a platform and side gage secured to the adjustable frameat one side of the bendingrolls, substantially as set forth.

2. In a machine for bending printers rules, the combination ofthesupporting Vmain standard A and a hinged and adjustable supportjusted bya set-screw, a, at the end of the oppo'sitel standard, substantially asset forth.

4. In a machine for bending printers rules, the combination ot' thesupporting main standard A, having side standards, D D', andguide-brackets D2, extending to one side thereof, with an uppercurving-cylinder, E, hinged and adjustable frame B, and lowerbendingrolls, B', the side standard D being stationary, while the sidestandard D' is laterally movable in .the guide-brackets D2, and adaptedto beretained thereby or to be thrown down for removing circnlarly-bentrules from the bending-rolls, substantially as specified.

5. In a machine for curving printers rules, the mainframe A, havingsidewise-extending lugs or brackets D2, provided with a fixed transverseguide-pin, d', and projections. d2, in combination with a laterallymovable side standard, D', having a slotted base, d, and with a fixedprojecting stop-pin, d3, on the main standard A, substantially asspecified.

Intestimony that I claim the foregoing as my invention I have signed myname, in presencevof two witnesses, this 22d day of April,

CHARLES V. STEINBAGH. Witnesses:
